# SDA Seeks PEREGRINE Sentry Industry Input

The Space Development Agency (SDA) published a sources-sought notice on September 23, 2026, for PEREGRINE Sentry, a ground-segment effort supporting resilient missile-warning and tracking operations in low Earth orbit. Responses are due **October 23, 2026 (15 days remaining)**. SDA anticipates an 18-month firm-fixed-price prototype Other Transaction Agreement (OTA), followed by a production OTA with a three-year base period and two three-year options.

- Interested firms should assess whether they can demonstrate classified-work capabilities and relevant experience in modular software, cloud and edge computing, DevSecOps, security, and systems integration, and submit a response by the stated deadline.
- The notice is a market-research opportunity, not an announced award. Responses can help SDA assess industry capacity for the planned prototype and potential production phase.
- A separate July 2026 PWSA Tranche 3 ground-segment letter contract, valued at a potential $400 million and awarded to General Dynamics Mission Systems, provides related SDA ground-segment procurement context; it is not identified as a PEREGRINE Sentry award.
